Nice article!

http://www.sportrider.com/sportbikes/2014-ebr-1190 rx-first-ride-review

From there:


quote:

The 1190RX uses Dell’Orto throttle bodies, but the entire EFI system was developed in-house by Erik Buell Racing, which could have either been a disaster or tremendous success. “We’re lucky in a couple of ways,” says Stefanelli. “One is we get resumes from really talented people every week. So we get to pick really good people. The other side of it is that the education system in the United States is doing a very good job of training people on control systems and software development. There’s a part of engineering called E-machines (electronic machines), and one of the best schools in the country happens to be an hour away from us. It’s the guys in the 21- to 28-year-old range that really have been taught very well how to do this kind of work. The other school systems internationally aren’t focused on it like the U.S. is and doesn’t have this young group of engineers coming through. I feel that we’re really lucky being a U.S.-based company, because what the United States has always been good about is ask, ‘Hey what’s the new cool thing, and we’ll train people to learn how to do that.’ And those people are now coming out of school, and we have access to them,” he confesses.




Anyone (annony or otherwise) willing to give a little more detail about the program and the school? I've thought recently that *exactly* this kind of thing is needed. I did this myself from scratch with an undergrad EE degree and graduate CS classes, but it would have made more sense to do it with a single integrated program.

Modern microcontrollers are such cool little platforms.

The only real problem I can see is that the clutch pull is overly firm, and heat emanating from the engine can be a bit overwhelming.

I didn't notice either.

I'd guess that those of us who rode tubers for any length of time would be unlikely to consider the RX's clutch pull "overly firm".

I didn't notice the heat problem, however, the RX is primarily ridden by the Mrs. Her comment to a guy at Laguna Seca who was whining about it: "I am a girl and I can do it." End of discussion.

The only time you really need they clutch would be down shifting.... maybe... and at stops.

It would change gears with just a little toe pressure on the shifter and slight roll off the throttle

As long as the bike is moving the RX does not get too uncomfortably warm. I put almost 200 miles on mine in 95+ degree Florida heat last month and only when going through 30MPH area's did I feel uncomfortable.

Another heat issue is right foot temperature. I had a 2009 1125CR and that thing cooked my right foot every time I rode it. I disliked it so much because of that I got rid of the bike. The RX seems to warm my right foot as well .. but nothing like the CR did.

I don't think you can wrap your legs around a 185 HP engine and except it not to be hot though ....

The magazine review comparing the RX to the Ducati Panigale actually said the RX heat was comfortable compared to the heat giving off by the Ducati. Making the Panigale basically unusable for street and commuter use.

I am sure as the engine breaks in it will run a bit cooler. My guess is the EBR Race ECM will ditch the insane emission standards the RX is meeting, richen up the mixture and run the engine cooler as well.

The Clutch pull .. I think everyone agrees .... is horrible. My Sportser (cable) and Monster (Hydraulic Brembo) are like butter compared to the RX. Wonder if swapping to a Brembo MC would help. I can't even imagine getting a shorty lever for the RX and make the clutch pool even harder.

The clutch is vacuum assisted so its only really firm when the engine is not running. At a stop light at idle holding it takes more strength than the feather light pull on other bikes but you get used to it in a day or less. Otherwise the transmission and clutch are like silk.


Engine heat?!?! What engine heat? One can compare the Panigale level of engine heat to anything other than sitting on the sun. The RX does get warm, but I'll put this way, in 95F weather of humid Houston Texas, one of the few places on earth where the ground is dry but the air is wet, at 5pm on a 6 lane super slap in stop and go traffic creeping at 15mph for a little over an hour. The RX was comfortable where as my riding partner on the 2012 ZX10r was miserable for two reasons. One his bike was cooking him, two it overheated and we had to stop and wait for it to cool down. Those fans may be loud and move a ton air, but they work!

95F and in stop and go traffic for an hour and your RX did not get uncomfortable? Just curious what you were wearing to not have had the heat affect you. I can assure you riding in Jeans and Work Boots and you fee the heat on my RX in the scenario you describe.

The clutch pull on mine is still a little higher than what I prefer, but it IS doable. And, for some strange reason, it is less than the RX that I demo'ed.

As for heat from the RX, I haven't really noticed anything approaching uncomfortable. If I move my feet around I can feel the hot air being expelled by the fans, which has been somewhat welcomed on cooler rides, but nothing approaching uncomfortable.

I really haven't found any nits to pick on the RX,

95F and in stop and go traffic for an hour and your RX did not get uncomfortable? Just curious what you were wearing to not have had the heat affect you. I can assure you riding in Jeans and Work Boots and you fee the heat on my RX in the scenario you describe.

I commute to work in a either a perf leather or mesh jacket, slacks with kneepads and a set of SMX-2 boots. Pleasure rides its usually perf leather and diamond riding jeans with either SMX-2 or 6 boots and knee pads. Anything described as spirited gets the full leathers, back protector, SMX-6. I always were a set of Knoxx Handroid gloves because kangaroo palms feel so NICE!

The Fan shrouds keep hot air out away from bike and rider. The frame gets hot but not RSV4 or ZX10 frame HOT, not even close. There are times when I can feel heat coming from under the seat near my thighs. There isn't anything there to get hot but the shock and air, so it must be hot air from the rear cylinder escaping there.

I rode an RSV4 for a day, the frame on that thing gets HOT! SCORCHING HOT! The whole bike gets pretty warm and the rear exhaust headers runs along the rear shock. Try changing the preload or compression after a ride and you will find out how hot that gets the rear shock.


The ZX10r exhaust radiator air back onto the engine and then out the fairing right onto my legs. So not only do you get the hot air that passes through the radiator, which heats the engine, but you also get the hot air from the headers and engine itself. The frame on the zx10r gets smoking hot too.

I used to think only XBs, 1125, and now the 1190 boiled their fuel because of the fuel in the frame design. What I have discovered is that both the ZX10r and RSV4 do as well, you need only listen to the tanks after a ride. The fuel cools faster because its in a plastic tank but it still gets hot enough to gurgle for a while.

Its all relative but to my mind and rear end, the RX is actually one on of the cooler running liter bikes. I think only the CBR1RR and RC8R may be better. The R1 and F4 and F3 800 all get silly hot so fast I thought something was wrong with engine but was normal. The Panigale is INSANELY, its not worth it, HOT in traffic. May as well ride a dwarf star or nuclear reactor.

I really haven't found any nits to pick on the RX

Wheel design makes them a PAIN to clean or keep clean rather. The strap over the trunk/pillion seat make it a hassle to remove and install. Front wheel appears to be filled with helium. No quickshifter(though the tranny ALMOST could live without it), hard to clean water spots after washing from the area inside the windscreen immediately behind the dash, the dash doesn't have variable display modes,and my number one nit to pick..... short service intervals.

With the exception of the service intervals I wouldn't change a thing.

I have seen an RX where the owner removed the Pillion strap .. it is not necessary .. thinking about removing mine.

Good points on the the other nit picks.

/\ Removed mine the first day, haven't looked back, well, I've looked back at it and decided it even looks better without.

5500 miles on it, and not once I have complained that the bike was getting hot. Seems cooler than my XB, and much, much cooler than the jap 1L bikes I've had.

Thought about it, but its perfect for man handling the bike while reaching for the rear stand. Like I said with the exception of the service intervals being half what I wish, I wouldn't really change much of anything. I would add some radiator and oil cooler guards, and that's about it. Very well designed machine.

Noone1569 - looks like you're going to catch and perhaps pass me, while my RX is in the shop for her first major service. I'm traveling for 3 weeks so may be we can compare stories on the major services. I got a set of Q3's waiting to be tried out on the track once I get back.
